Since Palin joined Republican John McCain on the Republican ticket there have been stories that she was once a member of the Alaska Independence Party, never had a passport or traveled overseas until last year, that her husband was arrested 22 years ago on a drunken driving charge, and that she pushed for $27 million worth of federal earmarks into a bill for the tiny town of Wasilla while she was its mayor.

The party's leaders and many of the delegates publicly expressed support for Palin and said the issues being raised so far are not enough to disqualify her. But privately, they are waiting to see how she performs.

"I think what a lot of Republican operatives and delegates here are asking is what else is out there about Gov. Palin?" ABC News' George Stephanopoulos told "Good Morning America" Tuesday.

"Was the vetting process complete and professional? ... And finally, what does it say about Sen. McCain's judgment that he chose someone with no national security experience?" Stephanopoulos said.
